Plasma display device

Abstract

The present invention relates to a plasma display panel device that includes a plasma display panel, a chassis base, and a heat-radiating medium disposed between the plasma display panel and the chassis base. The heat-radiating medium transfers heat generated from the plasma display panel into the chassis base. The heat-radiating medium is constructed to easily attach the chassis base to the plasma display panel, and to facilitate the separation of the chassis base from the plasma display panel. The heat-radiating medium further includes a first adhesive layer, a second adhesive layer, and a heat-radiating layer disposed between the first adhesive layer and the second adhesive layer. The heat-radiating medium can include a thermally conductive filler.
